dc.description.abstractUsing a metallic incurved structure, a wideband miniaturized metamaterial absorber (MMA) covering L-ferquency range (1-2GHz) is proposed in this paper. Simulated results show that the bandwidth of the MMA with absorptivity more than 90% is 1–2.74 GHz, and its relative bandwidth is over 93%. The size of the unit cell is miniaturized to 20 mm × 20 mm, and the profile is only 0.078λ (at the lower frequency of 1 GHz). Both simulated and experimental results show that high absorptivity for TE and TM polarization over a certain range of incident angles can be gained. By analyzing the effective impedance and the current distribution, the mechanism of the proposed MMA to attain broadband absorption is analyzed. The proposed MMA has a good application on UHF-RFID systems and 4G communications.en
